GAS LAMP AND HEATER.

SPECIFICATION forming part of Letters Patent No. 772,249, dated October 11, 1904.

Application filed October 31, 1903- Serial No. 179,328. (No model.)

To all) whom, it may concern:

Be it known that I, WILLIAM STANLEY Mo- LEWEE, a citizen of the United States, residing at Yardley, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Gas Lamps and Heaters, of which the following is a speciiication.

My invention relates to improvements in a gas lamp and heater.

The object of my invention is .to construct the same in such a manner that it may be used for illuminating purposes and when desired may be used for both illuminating and heating purposes.

A further object of my invention is to produce a light which has great illuminating power. This is done by having an extremely long stand-pipe in which the gas and air, which is admitted at the bottom of said standpipe, are thoroughly mixed together and by providing an extension to said stand-pipe above the burner to cause a strong draft.

Referring to the drawings, Figure 1 represents a side elevation of my invention when used for both illuminating and heating purposes. Fig. 2 is a view similar to Fig. 1, showing the lamp only in use and the heater dropped below the burner, the heater and the base being shown in section; and Fig. 3 is a sectional view as on line 3 3, Fig. 1.

In the drawings, A represents the standpipe, having a base A.

B represents the burner, consisting of an incandescent mantle.

The stand-pipe A is intended to be of sufiicient length so that when the base A is resting on the floor the burner B will be slightly above a table of ordinary height. The gassupply pipe A enters the base A and terminates below the end of the stand-pipe, so that air is admitted to the stand-pipe, where it is thoroughly mixed with the gas before they reach the burner. A flame of great brilliancy is produced by having the long stand-pipe between the point where the air is admitted and the burner.

An extension-pipe C is placed above the burner B to cause a draft, and thus increase the illuminating power of the burner. The extension-pipe C is supported by vertical bars 0, securedto a nipple a on the standpipe. The nipple a also forms a means of attaching the mantle. I

D represents the heater,which is cylindrical in form,and itis adapted to slide vertically upon the stand-pipe, so that it may be raised to the position shown in Fig- 1, where it incases the burner B and becomes very hot. A collar F, having a set-screwy", is provided for holding the heater in any desired position upon the stand-pipe. The heater D consists of the top cl and the bottom cl, each of which has a central opening which permits them to encircle the stand-pipe A and the top d to encircle the extension-pipe C when in the raised position. Between the said top and bottom portions is the body portion D having transparent panels D, and a door D which is also provided with transparent panels. Connecting-strips D which form a part of the body portion D, hold thetransparent panels in position. Said panels are preferably made of mica. The body portion is also provided at the top and bottom with apertures D* and D for ventilating purposes. A deflector D as shown in Fig. 2, is placed in thecenter of the body portion D of the heater, and as it is thus located immediately above the burner it becomes .very hot and tends to heat the upper part of the heater D. As the body of the heater is provided with transparent panels, the light produced by the burner will be effective for illuminating purposes.

The heater D constructed in the above manner afl'ords a large radiating-surface which becomes extremely hot when in the position shown in Fig. l and makes a very eifective heating device.

When it is desired to use my invention for illuminating purposes only, the heater D is lowered to a position on the stand-pipe below the burner, as shown in Fig. 2, which will leave the burner entirely exposed.

A shade G may be'used to an advantage with my invention when it is used for illuminating purposes. The shade may be removed or raised to the top of the extension-pipe C when the heater is in use.

The burner may consist of more than one mantle by using a different form of nipple a without departing from my invention.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of a stand-pipe, an extension-pipe, a burner interposed between the same, aheater adapted to slide vertically upon said stand-pipe and incase said burner, substantiall y as described.

2. The combination of a base adapted to rest on the floor, a burner, a stand-pipe connecting said base and said burner said stand-pipe being of sufficient length to bring the burner above the height of an ordinary table, and a heater to incase said burner and slide vertically upon said stand-pipe, substantially as described.

3. The combination of a base, a stand-pipe supported by said base, a burner formed on said standpipe, a heater, transparent panels in said heater, said heater adapted to slide vertically upon said stand-pipe and incase said burner, substantially as described.

4. The combination of a base, a stand-pipe supported by said base, .an extension-pipe, means of supporting said extension-pipe above said stand-pipe, a burner interposed between said stand pipe and said extension-pipe, a heater adapted to slide vertically upon said stand-pipe, transparent panels in said heater, a deflector located Within said heater midway between the top and the bottom of the same, and a collar encircling said stand-pipe adapted to support said heater upon said stand-pipe, substantially as described.

5. The combination of a base, a stand-pipe supported by said base, an extension-pipe, a burner located between said stand-pipe and said extension-pipe, bars supporting said extension-pipe, a heater adapted to slide vertically upon said stand-pipe and adapted to incase said burner, said heater consisting of a top and bottom each having a central opening through which passes said stand-pipe, a body portion connecting the said top and bottom, transparent panels in said body portion, a door located in said body portion and a deflector located midway between the said top and bottom, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM STANLEY MOLEWEE.
